Re: Matplotlib 3.10.0 for trixie?

Hi Alex, James, all,

Seems matplotlib migrated to testing now. I was thinking if it makes sense to do
an incremental 3.10.1+dfsg1-3 release.

There are 2 things that bother me that could be fixed in this release:

1. matplotlib has historically shipped /etc/matploblibrc to force tkagg and patched the code
to use this if there are no user defined rc files see [1]. However, this was not
handled properly via maintscripts so that'd mean over-writing user-modified /etc/matplotlibrc.

The backend detection logic is now better and I feel we should get rid of the "yield '/etc/matplotlibrc'" in
[1] and also stop shipping the conffile both and add in a rm_conffile to remove previously
installed /etc/matplotlibrc.

Probably also a d/NEWS to inform the sysadmin that this no longer works. It does not make
sense to me for a python lib to have a conffile.

2. matplotlib fails when there is empty gi directory. This is reported in #1101565 and James
has kindly provided a patch (thank you!).

Please let me know what you think?
